Chapter 1About the Modbus Protocol Converter

1-1 General

The protocol converter webSCADA device can be used to connect a Modbus/TCP master to one or several Modbus/RTU slaves and also view Modbus registers on a web-page. The module has a simple configuration interface to define which registers will be viewed on the web-pages. It also contains an alarm-handler to send alarms via email or SMS (requires a GSM-modem) and logging capabilities.

This application note describes how to create a configuration in the webSCADA module; it acts as a bridge from Modbus TCP to Modbus RTU, making it possible for a Modbus TCP based controller to connect with Modbus RTU based devices. The webSCADA is a device designed that is not only to provide the bridging function, but to also handle alarm management, data-logging as well as providing a web-based user interface for accessing data.

The protocol converter Modbus TCP/RTU supports an RS-232 connection through a 9-pole DSUB and RS-232 or RS-485 through the screw terminals. It also supports 10/100Mbps Ethernet through a standard Ethernet connector (RJ-45). It can be configured via a user-friendly web-interface or by using the Config utility.

Note: The Physical serial interface enabled can be changed through the Holding register no. 30 (Physical interface). See Appendix B - Internal registers for details.

Chapter 2Getting Started

2-1 Configuring the Protocol Converter

2-1-1 The Configuration UtilityThe Config utility is a PC-based configuration utility to set TCP/IP network settings in the device. This utility has the ability to scan the Ethernet network to find the connected devices and let the user set IP-address, net mask, protocol converter, DNS and hostname for each unit.

Installation System Requirements

• Pentium 133 MHz or higher;

• 5 Mbytes of free space on the hard drive;

• Win 95/98/ME/NT/2000/XP;

• Network Interface Card (Ethernet).

Installation Procedure

Download the program: Ascon_SW_DY-5xx1_Config.zip from the site www.ascon.it (section download/software). Install and run it.

Note: The first time you enter the Software Download area, you need to register yourself, by clicking on the register button.

2-1-2 Scanning for connected devicesFirst ensure that you have connected the devices you want to install on the same Ethernet network as the PC is connected to. Use standard Ethernet cables, straight-through or crossover cable depending on how you connect to the device. See pictures below for details.

Connecting the device to a hub or Switch

Connecting the device directly to a PC

When the Config utility is started, it will scan the Ethernet network to find the con-nected devices. All detected devices will be presented in a list in the main window. If you want to force a new scan for devices, you can press the “Scan” button.

IP: The IP address of the device;

SN: The subnet mask;

GW: The default protocol converter;

DHCP: Dynamically assigned IP address ON/OFF;

Version:Firmware version;

Type: Product type (DY WebServer);

MAC: The Ethernet MAC address.

Note: Use the “Advanced Options” button to enable the Config DHCP Server. This is useful when you have set DHCP to “On” in the device, but do not have a DHCP-server available on the network.

2-1-3 Changing IP settingsTo change the IP settings on a detected device, double-click on the device you want to configure in the list of devices. This will open up a dialog where you can enter the desired IP configuration.

To obtain the necessary information about IP address, subnet mask etc. please contact your network administrator.

Chapter 2 - Getting Started

Chapter 4Module Configuration

An important concept for the webSCADA is the usage of templates. This allows the user to define templates for different products and configurations, and then easily re-use and distribute them.

A template contains properties for available parameters in a device of a certain type. These properties includes: Parameter Names, Modbus register types and addresses, data scaling and presentation.

4-1 Workflow

Follow these steps to get your webSCADA operational:

1. Do all generic Setup, like assigning an IP-address (Setup/Ethernet), add/modify users (Setup/Users), configure the Modbus interface (Setup/Modbus)and set date/time etc (Setup/Regional).

2. Create a template (Configuration/Templates). A Template consists of one orseveral groups, and each group is a collection of Modbus Parameters.

3. Define your Devices (Configuration/Devices). A Device is simply a Modbusslave, with a unique Modbus address. For each Device, you apply a Template.

4. Create your Application! Now you can define your web-pages, alarms, logentries and bindings.

4-2 Create a template

Clicking on the “Configuration/Templates” link will bring up the following screen:

To create a template, click the “add template” button. This will create a “New template” in the list, which you now can edit. This will bring up the “Edit Templates” page where it is possible to add new groups (a collection of


18

parameters) and new Parameters. From this page it is also possible to backup, restore and delete templates.

Using the button “upload template” it is also possible to upload a template.

Note: You must always add a Group, before you can add a Parameter.

When you have created a Group, and at least one parameter, it is possible to edit the Parameter by clicking the “edit” button. This will bring up the following screen (Edit Parameter):

Note: Click on the “?” to view the online help.The “Edit Parameter” screen contains the following fields:

Name - Description of the parameter.

Type - Modbus type (Holding, Input, Coil, Discrete)

Address - Modbus address

Datatype - Defines the datatype of the Modbus register. Can be one of the following:

Unsigned 16 - 16-bit positive value

Signed 16 - 16-bit value, with sign

Unsigned 32 - 32-bit positive value. Most significant word (register) on low address.

Chapter 4 - Module Configuration

19

Signed 32 - 32-bit value, with sign. Most significant word (register) on low address.

Unsigned 32 (swapped) - 32-bit positive value. Most significant word (register) on high address.

Signed 32 (swapped) - 32-bit value, with sign. Most significant word (register) on high address.

Float - 32-bit floating point. (IEEE-754) Most significant word (register) on low address.

Float (swapped) - 32-bit floating point. (IEEE-754) Most significant word (regis-ter) on high address.

Double - 64-bit floating point. (IEEE-754) Most significant word (register) on low address.

Double (swapped) - 64-bit floating point. (IEEE-754) Most significant word (reg-ister) on high address.

Scaling - The Modbus register value will be divided by the scale value before presented on the web-page, logged or compared with for alarm.

It will be multiplied with the scale value before value is written to a slave device.

Examples: Modbus register value = 510, Scale value = 10 -> 51.0 will be viewed on web-page.Modbus register value = 5118, Scale value = 100 -> 51.18 will be viewed on web-page.Web-page input = 127.5 Scale value = 10 -> 1275 will be written to Modbus register.

Offset - The Modbus register value will be subtracted with the offset value before it is presented on the web-page, logged or compared with for alarm. If scaling is also in use it is done before the offset is subtracted.

The Offset value will be added to the value before value is written to a slave device. If scaling is also in use it is done after the offset is added.

Mask - Is used to mask out specific bits from the Modbus register, on the webpage the value is presented in binary. The Modbus register will be masked (logic and) and shifted to the right before the value is presented on the web-page, logged or compared with for alarm.


20

Examples: Modbus register value = 214 (D6 hex), Mask = 240 (F0 hex) -> 1101 (13) will be viewed on web-page.

Presentation - Defines how a value will be represented on a page. Available options are:

Show as valueThis option will read from the address and present the result at the view-page.

Writeable valueThis option reads the value from the address and presents it. There will be a set button next to the value at the view-page which makes it possible to write to the address.

Show with enumerationThis option will read the value from the address and present it with the corresponding enum string (See Enum below).

Writeable value with enumerationThis option will read the value from the address and present it with the corresponding enum string. There will be a drop down next to the value at the view-page where available enum strings will be selectable. A selected value will be written to the address.

Enum - here the enum variables is defined in following format [number]=[string]. Each enum is separated by a semi colon ';' with no blank spaces.

Examples: 0=Off;1=On0=Sunday;1=Monday;2=Tuesday;3=Wednesday;4=Thursday;5=Friday;6=Saturday

Number of decimals - Defines how many decimals to use for this point.

Valid range - defines min and max value for a write parameter. If a user tries to enter a value outside the range, a warning message will appear.

When you are finished with the Template, continue to the Device Configuration.

4-3 Device configuration

On the Device Configuration page, you define which Modbus slaves are attached to the webSCADA.


21

To add a device, click the “add device” button. This will bring up the following screen:

Name - A description of the device.

Template - Defines which template that should be associated with this device.

Modbus/TCP server IP address - The IP address for the Modbus/TCP server. If it is a Modbus/RTU device It should be left blank.

Modbus/TCP server port - The port to connect to the Modbus/TCP server. Modbus default is 502.

Modbus slave address - Defines the Modbus address of this device.

The next step is to create your webSCADA application, by defining the look of the web-pages and which alarms and log-parameters that should be available.

4-4 Pages

To create a new page, click the “add page” button. This will bring up the General Page Configuration menu:


22

On this page all page properties can be configured. A maximum of 20 Modbus points can be on each page. Next step is to define where to display the parameters. Simply click the “edit” button on the position you want to work with.

4-4-1 Adding parameters to web-pageNow select the Device, Group and Parameter and enter a description for this parameter, and finish by clicking the “save settings” button. To check that everything is OK, go to the “Select page” menu, select the page you have been working with and hit the “Go” button. You can also define a “presentation format” and “presentation scaling” on this page.

Presentation format - You can select a different presentation for a value on the presentation pages.

• Default Value is presented as it is configured in the Device template.

• Hexadecimal Value is presented in hexadecimal form.

• Binary Value is presented in binary form.

Presentation scaling - You can add an additional scaling on the value before it is presented on the web-page.

The value will be divided by the scale value before presented on the web-page. It will be multiplied with the scale value before value is written to a slave device.

Note: It is normally better to use the scaling in the Device template because that will also include logging and alarm.


23

4-4-2 PictureThis option lets you choose a picture to be presented on the page. The picture must not be more than 870 pixels wide and must be in gif, jpg or png-format. The picture will be sent to the device when you press the “Upload” button. To remove a picture from the device, press the “Clear” button.

Note: There are maximum 800kB available for pictures. On the General Page configuration section you can see how much space remains.

4-4-3 Page nameThis field can be used to give the page a more descriptive name. Click the “set as start page” button if this page should be the first page to be presented when logging into the module.

It is also possible to change name on the Page menu (default “Overview” and “Advanced Overview”).

4-5 Alarm configuration

The Protocol converter can send alarm messages with email, SMS or SNMP (traps).

(SMS alarms require an external GSM modem). The alarm functionality can be enabled/disabled on the Alarm configuration page. A maximum of 64 alarm parameters can be configured.


24

4-5-1 Defining alarmsTo add an alarm point, click on the “edit” button in the Alarm Configuration list. This will bring you to the following screen. Here you need to select which parameter to use, and define the trigger operation that will activate the alarm. You also need to define some properties like alarm class (1...10), and what strings should be in the subject and message field of SMS/Email alarms.

Trig On This configures the trig condition for the alarm parameter. It is possible to trigger on a Value (Higher than, Lower than, Equal to, Not Equal to, Change of Value) or on a bit-field (Any bit, Neither bit, All bits).

Alarm classCan be used to set different priorities on the alarm (class 1...10)

Subject Defines the text to be shown as Subject in the email/SMS

Message The body of the alarm message

SNMP Trap OIDthe last number in the SNMP OID that will be used when sending a SNMP trap. This can be used to uniquely identify the alarm (Mandatory) (the other part of the OID can be defined on the SNMP setup screen).


25

4-6 Log configuration

The DY webSCADA can be used to log Modbus registers. All data is stored in a CSV-file that can be uploaded to a computer for further analysis in e.g. Excel.A maximum of 64 parameters can be configured.

To start logging, click the “start” button.

Estimated Log TimeGives estimation about the time before the log file is full. This is an estimation, and will depend on the configuration, i.e. number of pages and parameters configured. The number and size of pictures for the pages will also affect the log file size.If the log interval is set to a predefined time, this will show as the estimated log time.

Log intervalDefines the time interval for between the samples that is saved to the log file.

Log type The log could be circular, which will fill the log with data. When full it can be sent. A new file will be created and the old one is deleted.

Maximum send log intervalThis will set the time when a log should be sent. If a time period is selected the log will be sent with this interval, e.g. at the same minute for every hour when At least every hour is chosen.

Send log files as E-mail attachmentIf a Send log interval is specified the log file is sent as an e-mail attachment to user that has configured this option, see paragraph 5-1 - Users at page 27.

Note: The log-file that is stored in the Protocol converter will contain historical data for a max. of two periods as defined in the “Send log files as E-mail attachment” property.i.e. if you set this to every day, the log-file in the Protocol converter will keep a maximum of two days historical data.See also Setup/Regional settings to make sure you have the correct settings for list separator and decimal symbol.

To add a log-point, click the “add log parameter” button, and then the “edit” button. This will bring you to the “Edit Log Entry” page.


26

Now you can select the Device/Group/Parameter you want to log, and also enter a description for this Log Entry. To finish, click the “save settings” button.

4-7 Bindings

Bindings are a feature that allows you to copy parameters from one Modbus device to another. To add a binding, click the “add binding” button.

On the “Add Data Binding” screen you choose the Source and Destination parameter, and the interval for the copying of data.

27

Chapter 5Module Setup

If you click on the Setup menu option, a sub menu will appear. Here you can do all nec-essary setup for things like user administration, modem settings and TCP/IP settings.

5-1 Users

If you press the “Users” link you will be transferred to the Users administration page. Here you can add, edit and remove users. To add a user, press the “add user” button, and to modify/remove a user click on the user you want to modify/remove.


28

Here you can enter the User ID (used on the login screen), name, contact info and a password.

If an e-mail address is entered, then alarms will be sent to this address (if user is configured as an alarm recipient and e-mail alarm is enabled).

If a mobile number is entered, then SMS-alarms will be sent to this number (if user is configured as an alarm recipient and SMS-alarm is enabled).

To configure a user as an alarm-recipient, enable one or more of “Alarm classes” (Class 1-10).

The user will only receive alarms that match this selection.

The “Receive log files via E-mail” option configures whether this user will receive logs via Email or not. See Configuration/Log (section 4.6) for more details about this function.

The language selection defines which language will be used for this user.

The user level defines what the user can do on the web-pages:

Read View pages but can't do any configuration or modify Modbus Registers

Write Can view pages and modify Modbus registers, acknowledge alarms.

Admin Read, Write and also configure the module (templates, devices, pages, alarms, log, and bindings)

Super AdminRead, Write, Admin and setup module like users, modem and modbus settings.

Note: To add/edit users, you must be logged in as a user with Super admin access.

5-2 Modbus settings

If you press the Configuration/Modbus menu you will be presented with the following view:

Serial Settings (Modbus RTU/ASCII)

Transmission modeSelects Modbus RTU or Modbus ASCII

Slave Response TimeoutThe time that the module will wait for a response from a slave, before a Serial timeout will occur. (Default 1000 ms)

Physical InterfaceEIA-485 or EIA-232

Baudrate 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600 or 115200 bps.

Character FormatSelect number of stop bits and if parity should be enabled (Odd, Even).

Delay between pollsTime to delay between Modbus messages.

Character delimiterNumber of milliseconds between characters in the Modbus frame. Set to zero to use standard Modbus (3.5 characters)

Force function code 15 when writing single coilIf this option is Enabled, all writes to coils will be done with function code 15. (Useful if slaves don't support function code 05).

Force function code 16 when writing single registerIf this option is Enabled, all writes to registers will be done with function code 16 (useful if slaves do not support function code 06).


30

Ethernet Settings (Modbus TCP)

Port numberWhich port to use for Modbus TCP communication (502 default).

Gateway RegistersThe address to the gateway internal registers (if enabled). See section 5.2.1 for details about the internal registers.

Server Idle TimeoutThis parameter gives the idle timeout in seconds for the Modbus/TCP connection. If the protocol converter does not receive any Modbus/TCP query within this time the connection will be closed. (Default value is 60 seconds).

IP AuthenticationThis can be used to configure the IP-number that is allowed to connect to the Gateway.

Note: It is of great importance to ensure at the time of the procedure of assigning Modbus device addresses, that there are not two devices with the same address. In such a case, an abnormal behavior of the whole serial bus can occur, the Master being then in the impossibility to communicate with all present slaves on the bus.

5-2-1 Internal RegistersIf Gateway registers are enabled, queries sent to that address will not be forwarded to the Serial Modbus/RTU network; the protocol converter will respond to these queries by it self.

See Appendix B for a list of the internal registers.

Valid Modbus commands for internal registers:

Note: The internal registers are also available as an “internal template”, i.e. the registers can be used on presentation pages and as alarms/log entries.

Command Name3 Read Holding Registers6 Preset Single Register

16 Preset Multiple Registers

5-3 Modem settings

On this page you setup an external modem (optional) that can be either a GSM/GPRS modem or an analogue modem (PSTN).

5-3-1 Generic modem settingsStart with selecting the correct type of modem attached (GSM, Analogue, GPRS). Also set the desired baudrate that the webSCADA should connect to the modem with.

In this section you can also enter a PIN-code for the GSM-modem. Clicking on the “modem info” button will bring up a screen with some details about the modem (Signal strength etc).

5-3-2 Dial-up/GPRS settingsIn this section you find configuration to allow the webSCADA to connect to Internet using a modem.

Connection trigger - Specifies whether the webSCADA should always be connected to Internet using the modem, or only connect when there is an alarm or event.

Host to ping - address to the Host that the webSCADA will ping when sending keep-alive messages for the GPRS connection.

Ping timer - Specifies the interval for the keep-alive messages. (Set value as high as possible to avoid unnecessary GPRS traffic).

Access Point Name (APN) - This is the gateway for all GPRS traffic. Contact your GSM/GPRS operator for information about this.

Phone number - Phone number to dial (e.g. to an Internet Service Provider, ISP).

User name - This is the username your ISP have assigned to you.

Password - Password to log into the ISP network.


32

5-3-3 Dial-in settingsThe dial-in functionality can be used when someone wants to view the web-pages in the webSCADA over a modem-link.

Local IP-number - This is the IP-number of the webSCADA, which the remote client will see when creating the PPP-connection.

Remote IP-number - This is the IP-number that will be assigned to the remote client, when creating the PPP-connection.

Username - This is the login that the remote client will use when creating the PPP-connection.

Password - This is the password that the remote client will use when creating the PPP-connection.

Note: If you want to view the web-pages on a slow link (like GSM/GPRS), there is a special low-bandwidth version of the pages available. Enable this functionality on the Setup/Webserver page.

5-4 Regional

The Regional page contains configuration for time and date, generic module information and also configuration for how the log file list separator and decimal symbol should be represented.

5-4-1 Time and dateConfigures the real-time clock on the module. The clock will continue to work during power-loss (max. 1 week). To use NTP (Network Time Protocol), enable it and enter an NTP-server (or use the default configuration). Also set the update interval (how often NTP will synchronise the time).

5-4-2 NumbersThe list separator and decimal symbol should be selected so it matches the configuration on the computer where the file will be analysed.


33

5-4-3 Module informationThe “Site Name” string can be used to add information about where the module is located (address, building id etc.). The site name is shown left to the log out button in the user interface header.

The “More information” field can be used to do notes about the installation.

5-5 Email Setup

The following configuration properties are available:

Sender - From field in the alarm mail. Example “DY - WebSCADA”

Reply path - The E-mail address to send a mail to when someone reply on an alarm mail.

SMTP server - IP-number or domain name to the SMTP server that the module should use when sending E-mails. If domain name is used make sure that you have entered a DNS under the Network configuration.

SMTP Authentication

- Authentication method: Auto, plain, login or cram-MD5- Username- Password

5-5-1 SMTP AuthenticationIf the SMTP server require authentication you should enable SMTP Authentication. There are several types of authentication methods supported by the module:

auto - The module automatically select the best method supported by the SMTP server.

plain - a simple non-encrypted method supported by most SMTP servers.

login - a simple non-encrypted method supported by most SMTP servers.

cram-md5 - a more secure login method where the username and password is encrypted (this method is not supported by all SMTP servers).


34

Note: “auto” will not work if only plain and login is supported by the SMTP server, because the module find these methods too insecure, in that case “login” or “plain” must be must be set explicit.To verify the setup, use the Test E-mail functionality. Clicking on the “send” button will generate a test e-mail.

5-6 SNMP Setup

The SNMP Setup page contains configuration to be able to send SNMP traps.

Host - The SNMP manager to which SNMP traps should be sent

Port - The port number on the SNMP manager to which traps should be sent

Community - SNMP community used

Enterprise OID - The enterprise OID (Object Identifier) that should be used in the SNMP traps sent. This is the common part of the Enterprise OID that is the same for all traps sent from the webSCADA. Use the OID setting when configuring alarms to set a unique OID for each alarm.

5-7 Web-server Setup

The Webserver Setup page contains a configuration to change the port number of the internal web-server in the webSCADA and also enable/disable the low bandwidth pages.

Extra webserver port - To connect to the Extra webserver port the URL should have a colon (:=) followed by the new port number, i.e. http://10.10.10.30:8080 where 10.10.10.30 is the IP number or DNS address to the Protocol converter and :8080 the new port.

Compression on web pages - This feature is only used for the extra webserver port. When set to enable the Protocol converter check if the browser support compressed pages, and if that is the case will send compressed pages. This feature will increase the workload of the Protocol converter, why it is enabled as default. There is an option to disable compression and the pages will be sent as normal web pages, which always is the case for the standard web server port 80.

If it is set to force web pages will always send compressed regardless the support of the web browser.

The information that a web-browser supports compressed data could sometimes be removed when passing some firewall or proxy servers. This is true for the default setting port 80 in Microsoft ISA servers. To ensure that compressed web pages are sent anyway the option force should be set. Most web-browsers support compressed data.


35

Auto update value and status - This feature is only used for the extra webserver port. To limit the amount of data transferred and increase speed when using low bandwith, i.e. modem connection, the data and values could be set to be updated by clicking the refresh button only. This button is shown at the upper right corner of the user interface.

Automatic logout time - Defines the time-interval before a user is logged out from the web-server.

� WARNINGIf domain name is used make sure that the DNS setting for the Ethernet connection is correct.

Notes: 1. The webserver always listen to port 80. When using modem connection, compression on web pages will always be enabled and Auto update will always be disabled to improve response time, and the refresh button has to be clicked to update values and status.

2 Changing the Webserver port will disable Webserver on default port 80.

5-8 Ethernet (TCP/IP) settings

If you press the Configuration/Network link you will be presented with the following view:

On this page you can view and change the TCP/IP network settings in the module. These settings are the same as the ones set by the NetBiter Config utility.

Appendix CSNMP

If SNMP Alarms is enabled, see section 7.5.1 page 26, all alarms will be sent as SNMP traps to the specified on the SNMP page, see section 6.6 on page 19.The OID is sent in the following format in numbers:

.1.3.6.1.4.1.23312.1.1.2 [IP address][event]

.1.3.6.1.4.1.23312.1.1.[trap_id][trap_data]where:

23312 is enterprise ID 1.1 is products DY

webSCADAand where event:

1 = Alarm set2 = Alarm cleared

A trap id is divided into five messages with following trap data:

#1 Alarm ID #2 Alarm descriptions #3 Class ID (1...10) #4 Class description #5 Alarm severity;

where:0 = indeterminate1 = critical2 = major3 = minor4 = warning5 = cleared .

See the pictures for example of SNMP trap sent an alarm to warning of high temperature from a DY.


44

To try out the SNMP functionality the software Trap Receiver could be used. This program can be found at http://www.trapreceiver.com. Please, check the license for the software. It could be used to examine a trap sent to a PC to better understand the SNMP functionality of the Protocol converter DY webSCADA.
